Fax and Modem over IP

For many enterprises in different industries, fax and modem transmissions remain one of the most important communication methods. In areas such as finance, government, law, health, real estate, offshore, etc., fax and modem over IP are one of the essential ways to transfer a large number of documents and data, on a daily basis.

Keeping the reliability and quality of those communications without risk while migrating from TDM-based PBXs to IP telephony networks can be a challenge. During the transition from traditional telephony lines to VoIP in the operator network, or the existing legacy telephony systems to the IP-PBX and IP-phones inside enterprises, some interoperability issues may occur between different fax protocols and standards used by the VoIP systems and the enterprise.

When it comes to faxes and modems, reliability and security are pre-requirements for many businesses that cannot suffer from failure or loosing data. Media5 solutions offer trustful connectivity and communications to the new IP telephony infrastructure in many scenarios and are adaptable to specific enterprise needs.
